1. The Internet-Standard Management Framework
For a detailed overview of the documents that describe the current
Internet-Standard Management Framework, please refer to section 7 of
RFC 3410 [RFC3410].
Managed objects are accessed via a virtual information store, termed
the Management Information Base or MIB. MIB objects are generally
accessed through the Simple Network Management Protocol (SNMP).
Objects in the MIB are defined using the mechanisms defined in the
Structure of Management Information (SMI). This memo specifies a MIB
module that is compliant to the SMIv2, which is described in STD 58,
RFC 2578 [RFC2578], STD 58, RFC 2579 [RFC2579] and STD 58, RFC 2580
[RFC2580].
2. Introduction
The OSPF MIB is defined as [RFC4750] and the ISIS MIB as [RFC4444].
On the other side, MPLS/GMPLS based traffic engineering has so far
extended OSPF/ISIS routing protocol with TE functionality [RFC4202],
[RFC3630], [RFC4205], [RFC3784]. To manage such MPLS-TE/GMPLS
networks effectively, routing information associated with MPLS/GMPLS
TE parameters (TED) is preferred for the network management, however,
there is no clear definition of MPLS/GMPLS TE information in existing
MIBs related with OSPF/ISIS.
This memo defines the Management Information Base (MIB) objects for
managing TED in support of MPLS-TE/GMPLS for use with network
management protocols.
This MIB module should be used in conjunction with OSPF/ISIS MIB as
well as other MIBs defined in [RFC3812], [RFC3813], [RFC4802],
[RFC4803] for the management of MPLS/GMPLS based traffic engineering
information.
3. Overview
3.1 Conventions used in this document
The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT",
"SHOULD", "SHOULD NOT", "RECOMMENDED", "MAY", and "OPTIONAL" in this
document are to be interpreted as described in RFC-2119 [RFC2119].
3.2 Terminology
Definitions of key terms for MPLS OAM and GMPLS are found in [RFC4377,
RFC3945] and the reader is assumed to be familiar with those
definitions which are not repeated here.
3.3 Acronyms
GMPLS: Generalized Multi-Protocol Label Switching

4. Motivations
The existing OSPF, MPLS and GMPLS MIBs do not provide for the
management of all of the extensions to the OSPF protocol. To manage
MPLS/GMPLS TE attributes, MIB objects to indicate such MPLS/GMPLS TED
is significant.
5. Brief description of MIB Objects
The objects described in this section support the management of TED
described in [RFC4202], [RFC4203] and [RFC4205] for GMPLS extensions
as well as in [RFC3630] and [RFC3784] for MPLS/GMPLS.
5.1 tedTable
The tedTable is basically used to indicate TED information of OSPF-TE
or ISIS-TE. However, this table does not contain the information of
Local/Remote interface IP address, Interface Switching Capability
Descriptor and Shared Risk Link Group information within the sub-TLVs
for the Link-TLV.
5.2 teLocalIntIpAddrTable
The teLocalIntIpAddrTable is identical to the Local interface IP
address information in a sub-TLV for the Link-TLV. This is
independently defined, because the Interface IP Address sub-TLV may
appear more than once within the same Link-TLV.
5.3 teRemoteIntIpAddrTable
The teRemoteIntIpAddrTable is identical to the Remote interface IP
address information in a sub-TLV of the Link-TLV. This is also
independently utilized, because one or more local interface IP
address sub TLVs may exist in the same Link-TLV.
T. Otani et al. Expires Jan. 2009 [Page 4]
Internet Drafts draft-ietf-ccamp-gmpls-ted-mib-04.txt July 2008
5.4 teSwCapTable
The teSwCapTable represents Interface Switching Capability Descriptor
information. This is independently defined due to the possibility of
multiple appearances of the sub TLV within the same Link-TLV.
5.5 teSrlgTable
The teSrlgTable contains the Sub-TLV information of Shared Risk Link
Group (SRLG) information. This is separately defined, because more
than one sub TLVs may appear in the same Link-TLV.
6.Example of the TED MIB module usage
In this section, we provide an example of the TED MIB module usage.
The following indicates the information of a numbered TE link
originated in a GMPLS controlled node. When TE link information is
retrieved in a MPLS network, GMPLS specific objects such as
teLocalIntAddrTable, teRemoteIntAddrTable, teSwCapTable and
teSrlgTable are not supported.
Note that the TE MIB modules are only limited to "read-only" access
except for tedNotificationEnabled and tedNotificationMaxRate. The TED
MIB is designed to be independent of OSPF or ISIS MIBs, however each
TE information is belonging to a node or a link, which is managed by
the routing protocol. Therefore it should not be locally changed
without triggering from the routing protocol.

8. Security consideration
There are no management objects defined in this MIB module that have
a MAX-ACCESS clause of read-write and/or read-create. So, if this MIB
module is implemented correctly, then there is no risk that an
intruder can alter or create any management objects of this MIB
module via direct SNMP SET operations.
Some of the readable objects in this MIB module (i.e., objects with a
MAX-ACCESS other than not-accessible) may be considered sensitive or
vulnerable in some network environments. It is thus important to
control even GET and/or NOTIFY access to these objects and possibly
to even encrypt the values of these objects when sending them over
the network via SNMP. These are the tables and objects and their
sensitivity/vulnerability:
- teTEDtable, teLocalIntAddrTable, teRemoteIntAddrTable,
teSWcaptable and teSrlgtable contain topology information for the
MPLS/GMPLS network. If an administrator does not want to reveal this
information, then these tables should be considered
sensitive/vulnerable.
SNMP versions prior to SNMPv3 did not include adequate security. Even
if the network itself is secure (for example by using IPsec), even
T. Otani et al. Expires Jan. 2009 [Page 22]
Internet Drafts draft-ietf-ccamp-gmpls-ted-mib-04.txt July 2008
then, there is no control as to who on the secure network is allowed
to access and GET/SET (read/change/create/delete) the objects in this
MIB module.
It is RECOMMENDED that implementers consider the security features as
provided by the SNMPv3 framework (see [RFC3410], section 8),
including full support for the SNMPv3 cryptographic mechanisms (for
authentication and privacy).
Further, deployment of SNMP versions prior to SNMPv3 is NOT
RECOMMENDED. Instead, it is RECOMMENDED to deploy SNMPv3 and to
enable cryptographic security. It is then a customer/operator
responsibility to ensure that the SNMP entity giving access to an
instance of this MIB module is properly configured to give access to
the objects only to those principles (users) that have legitimate
rights to indeed GET or SET (change/create/delete) them.
9. IANA Considerations
The following "IANA Considerations" subsection requests IANA for a
new assignment under the transmission subtree. New assignments can
only be made via a Standards Action as specified in [RFC5226].
9.1 IANA Considerations for TED-MIB
The IANA is requested to assign { transmission XXX } to the TED-MIB
module specified in this document.
